Highest temperature in Shanghai on July 2?

Platform comparison

Market context

On 2 July 2026, the Shanghai Pudong International Airport Station will record its peak daily temperature in degrees Celsius, a real-world event that determines the outcome of this prediction market. Historical data confirms that July in Shanghai is consistently hot and humid, with average highs ranging from 26–31°C and frequent peaks exceeding 35°C, as seen in 2025 when temperatures reached 38°C[2][7]. Given that the crowd-implied probability for a 26°C outcome sits at 0%, this aligns with comparable cases where July highs rarely dip to such low levels, making the current pricing a rational reflection of seasonal norms rather than an anomaly[2][8].

Traders should monitor the official weather schedules released by the National Weather Service and Wunderground, which provide the definitive resolution data for this market[3]. Recent climate reports indicate that 2026 has followed typical summer patterns, with daily highs in Shanghai Pudong consistently ranging between 80°F and 93°F (approximately 27–34°C), reinforcing the low likelihood of a 26°C peak[6]. While no specific weather announcements are pending for this date, the dependency on real-time sensor data from Wunderground means that any sudden shifts in atmospheric conditions or cloud cover could alter the final reading, though such deviations remain statistically improbable given the established seasonal baseline[2][6].

The market's traction is directly tied to the funding flows that drive its book depth, particularly as users navigate deposit and withdrawal rails like Klarna and SEPA. As payment friction decreases through streamlined on-ramps, more capital enters the book, allowing traders to position more aggressively against the 0% probability. This liquidity surge ensures that the market remains efficient, with the price accurately reflecting the high certainty that Shanghai’s July temperatures will far exceed the 26°C threshold, leaving little room for speculative error in the final settlement.
